Abstract

A new method of accumulating thermal energy in the bowels of the Earth to ensure stable, continuous operation of a solar thermal power plant.

The solution of underground storage of heat will be useful for:

• • Expansion of the solar thermal energy geography.
  • Extension of the scope of existing geothermal technologies.
  • Combining the mutual interests of energy-generating and oil-and-gas companies on the platform of new opportunities for using advanced technologies of each other.

Claims

1. A method of underground storage of a thermal agent in a natural reservoir characterized in that in order to provide the continuous and uniform operation of a solar thermal power unit in a multi-day mode, as well as to ensure the necessary volumes and optimize the costs for maintaining of the thermal agent stream continually, capacitive-filtration properties of the reservoir improve by directional fracturing.

2. A method of claim 1, characterized in that to restrict of water inflow from peripheral zones of reservoir sections use the waterproofing technologies.

3. A method of claim 1, 2 characterized in that to the maintaining reservoir pressure the spent thermal agent after exiting the power generator turbine, is pumped into the external zone of the storage.
